The INIVEN PTR-1500 is available in two configurations for use in different types of applications objectives. Configuration 1 This single channel configuration provides a guard and trip frequency audio tone over a single telecommunications channel between two substations for the protection of a single line section.

A single chassis is located at each end of the protected line section and contains the following modules:

• DC/DC power supply module • Line Interface module • Hybrid Splitter (4 wire) module • Transmitter module • Receiver module • Logic module • Contact Output module • Solid State Output module

Configuration 2 This configuration provides dual independent channels, each having individual guard and trip frequencies and outputs. This unit may have either a 8 wire or 4 wire hybrid connection to the communication circuits to the remote terminal(s). In Application 2, a configuration 2 chassis is located at the Bus 2 location and provides trip and guard signals to the configuration 1 chassis located at the Bus 1 location over the channel 1 transmitter. The same configuration 2 chassis provides separate trip and guard signals to the configuration 1 chassis at the Bus 3 location over the channel 2 transmitter. The inputs to the channel 1 and channel 2 transmitters are independent of one another. The outputs of the channel 1 and 2 receivers are also independent of one another.

4 | P a g e

For this application, a single Configuration 2 chassis is located at the Bus 2 location and contains the following modules:

• DC/DC power supply module • Line Interface module • Hybrid Splitter (8 wire) module • Transmitter module • 2 Receive modules • 2 Logic modules • 2 Contact Output modules • 2 Solid State Output modules

In Application 3, a configuration 2 chassis is located at both Bus 1 and Bus 2 locations and provides 2 channels of trip and guard signals to the configuration 2 chassis located at the remote terminal. In this application the Channel 1 signals can be used for permissive transfer tripping while the Channel 2 signals can be used for direct transfer tripping. The inputs to the channel 1 and channel 2 transmitters are independent of one another. The outputs of the channel 1 and 2 receivers are also independent of one another.

INSTALLATION Unpacking Two configurations of the PTR-1500 may be supplied. Both configurations are supplied as an individual chassis. Each unit will be packed in its own shipping carton. Inspect the carton for possible damage in transit. Open each carton carefully and remove the chassis. Inspect the equipment for possible damage. Verify all items of value have been removed from the carton prior to discarding the packing material. Should transit damage be found, please notify INIVEN immediately. (1-800-526-3984) NOTE: It is suggested the carton be retained for possible onward shipment.

Mounting Two screws are required per mounting bracket (four total per chassis) and are not supplied with the unit. Install the chassis in the desired location and securely tighten all four screws. Spacing of the mounting holes is compliant with EIA and DIN standards. NOTE: Adequate ventilation is required for reliable operation of electronic equipment.

Temperatures within the equipment room should be kept between -30oC and +70oC to assure reliable operation.

Electrical Connections User connections are made on the rear of the chassis through barrier and screw terminal blocks. Refer to the end of this section or to the drawings that come with the unit for specific wiring details. References made to terminal blocks are via terminal block numbers. Terminal block TB-1 terminal 1 is referred to as TB1-1. Terminal block TB-1 terminal 2 is referred to as TB1-2 and so on. Various methods of making the connections to the terminal blocks may be used and are based on local practice. Lugs or bare wire may be used. Make sure to tighten all connections and insure exposed wires and/or lugs do not touch each other or the chassis. To reduce the possibility of induced currents on the Trip input leads, it is recommended that shielded twisted pair wires are used with the shield grounded at the PTR-1500 end only. The Trip input leads and the communication cables should be bundled separately from each other and the other leads. CAUTION: FOR SAFETY REASONS, ELECTRICAL POWER ON THE LEADS BEING CONNECTED TO THE UNIT SHOULD BE DE-ENERGIZED DURING INSTALLATION.

7 | P a g e

Inputs & Outputs TRIP INPUT The Trip input current is limited to 10 ma. A resistor in series with the optical isolator on each of the Trip inputs is used to limit the current. To produce a Trip, the battery voltage must be within 50% of the input battery voltage. TRIP & GUARD OUTPUTS Configuration 1 Four (2 Trip and 2 Guard) form C contact outputs are provided. Two (1 Trip and 1 Guard) solid state outputs are also provided. Configuration 2 Eight (4 Trip and 4 Guard) form C contact outputs are provided. Four (2 Trip and 2 Guard) solid state outputs are also provided. Please consult the factory when changes to a PTR-1500’s factory configuration are being made. STATUS RELAYS Configuration 1 Four status relay alarms, each with a single set of SPDT (form C) contacts are provide the following:

• Alarm 1 (AL) – Master alarm indicating receiver failure to detect a signal, power failure (all other relays will also de-energize) and long term noise/interference on the incoming signal.

• Block 1(BL) – Detection of a corrupted signal • Loss of Signal (LOS) – Indicates received signal level is below the set threshold. • Transmitter Fail (Trans Fail) – Indicates the transmitted signal is below the setting threshold.

Configuration 2 Two sets of the four status relay alarms listed above are included. One set for each channel. Each relay is a single set of SPDT (form C) contacts. NOTE: All of the status relays are energized during normal operation. Contacts are closed in their de-energized state. AUDIO TONE LINES Configuration 1 The unit is supplied for four-wire operation. Configuration 2 The unit is supplied for eight-wire operation.

8 | P a g e

CAUTION: GROUNDING THE EQUIPMENT IS IMPORTANT FOR BOTH SAFETY REASONS AND RELIABLE OPERATION. CONNECT A 16 AWG OR LARGER WIRE BETWEEN CHASSIS GROUND AND EARTH GROUND UTILIZING THE SHORTEST PATH TO KEEP RESISITANCE AND INDUCTANCE TO A MINIMUM. NOTE: Verify the battery voltage matches the input power requirements of the units. NOTE: Double-check all connections for tightness and correctness, including polarity as applicable. Replace all protective covers supplied.

2. Set the multimeter for dBm measurement. 3. Connect the positive multimeter lead to the TX OUT 1 test point on the front of the TRANS module, and connect the negative lead to the COMMON test point. 4. Note the indication on the multimeter. This is the output of Channel 1. Set to +2dBm (this will result in 0dBm at the output). 5. Connect the positive multimeter lead to the TX OUT 2 test point on the front of the TRANS module, and connect the negative lead to the COMMON test point. 6. Note the indication on the multimeter. This is the output of Channel 2. Set to +2dBm (this will result in 0dBm at the output). 7. Disconnect the multimeter test leads from the TRANS module.

Receiver 1

8. Connect the positive multimeter lead to the REC OUT test jack on the front of the REC module 1. Connect the negative lead to the COMMON test point on the same card. The meter will read the incoming signal. 9. Verify that the unit is receiving a steady incoming Guard signal (no Trip or line noise). 10. Press and hold SENS SET switch on the REC module front panel. 11. Using a small screwdriver or potentiometer adjustment wand, slowly turn SENS potentiometer counterclockwise until the GUARD LO indicator begins to flicker. 12. Release the SENS SET switch.

Receiver 2

13. Repeat steps 8 through 12 for the REC module 2. NOTE: The above procedure will set your Receivers for a 20db dynamic range. If the above procedure was successfully completed, the terminal is working properly. If the procedure could not be completed, or if a malfunction is suspected, refer to the Instruction Manual maintenance information in Section 7 and the information on the individual cards in Section 4 to determine the source of the problem. Once the problem is located and corrected, repeat the initial startup procedure to assure that the unit is functioning properly.
